Use the \definetypeface command to load the math font. Math fonts
always use special
settings or load additional settings which are missing when you use
\definefontfamily.
\definetypeface [mainface] [mm] [math] [pagella]
\definetypeface generates the same error message if the font size is
changed:
\definefontfamily [mainface] [rm] [TeX Gyre Pagella]
\definefontfamily [mainface] [ss] [TeX Gyre Heros]
\definetypeface [mainface] [mm] [math] [pagella]
%% 8pt works
\setupbodyfont [mainface, 8.5pt]
\starttext
   \bold{\math{x_y}}
\stoptext
You get the same error with Latin Modern as soon as you use a non 
predefined font size in combination with bold math.

%%%% begin example
% \starttypescript [math] [default] [size]
%   \definebodyfont [8.5pt] [mm] [default]
% \stoptypescript

\setupbodyfont[8.5pt]

\starttext

\im{x_y}

\mb\im{x_y}

\stoptext
%%%% end example
